I have tried playing both solo and online, with different weapon loadouts and body types. It isn't that I can't wipe out those mediocre A.I. bots, it's that they seem to respawn too quickly and too close to the objective. Once I wipe out the group of six or eight or however many baddies there are, there is no time to complete the objective before they roll back in. I either find cover and kill them as they respawn until I run out of ammo, or I try to run in and complete the objective to get gunned down by instant-reappearing bots while doing so. My four fumbling A.I. allies seem to do nothing but dance a jig in front of the enemy's firing line.
